TYB
Going to dig some moar on flight radar 24 just to be sure. But working theory is that the H53 seen on ADS-B was search rescue for already downed V-22. Unless can find V-22 ADS-B data in history then am going to assume was flying dark (no ADS broadcast) at the time of the crash. USMC has already tweeted nuke rumors were just rumors. FWIW. See embed video for evidence of H53 responding to crash.
